ABSTRACT:
A spray nozzle for discharging liquid in a spray pattern onto a ground surface includes a structure to obtain optimum diffusion of the liquid droplets in the spray pattern. The spray nozzle includes a diffuser plate having an upwardly extending diffuser blade thereon. The diffuser plate and blade are adjustable vertically and longitudinally in the discharge end of the nozzle to enable variation in the diffusion characteristics of the liquid discharged from the nozzle. The diffuser plate is also removable for replacement with other plates having alternative diffuser blades. The structure enables variation in the spray pattern of the liquid passing between the diffuser blade and the inner surfaces of the side walls of the nozzle by changing the location of the diffuser plate and blade in relation to the discharge end of the side walls of the nozzle or by using another plate having a different diffuser blade for different diffusion characteristics.
